Issue Details

I am calling a MATLAB script in LabVIEW using Call MATLAB Function node and I am getting the following error. I am confident the MATLAB script file exists and the path uaws is correct. How should I resolve this issue.

Error 1739 occurred at an unidentified location

Possible reason(s):

Solution

Although the MATLAB script is being called by LabVIEW, under the hood, the MATLAB script is executed by MATLAB itself and the result is feedback to LabVIEW. Hence, kindly ensure the file path, file name, and function name are following MATLAB's naming convention. This error happens commonly due to the file path, file name, or function name not following MATLAB's naming convention.
